If there has GridViewSelectColumn, The data context can not be accessed by other thread

[Chen]

Hello,

I have a gridview below. The code "await Task.Run(() => { View.clear(); });" throw an exception:"The calling thread cannot access this object because a different thread owns it." But if I remove "<telerik:GridViewSelectColumn/>", it​ works, please tell me how to fix it? Thanks.

<telerik:RadGridView Name="view" ShowGroupPanel="False" Margin="10" IsReadOnly="True" ItemsSource="{Binding View}" AutoGenerateColumns="False" SelectionMode="Extended">
                <telerik:RadGridView.RowStyle>
                    <Style TargetType="telerik:GridViewRow">
                        <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=OneWayToSource}"/>
                    </Style>
                </telerik:RadGridView.RowStyle>
                <telerik:RadGridView.Columns>
                    <telerik:GridViewSelectColumn/>
                    <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}"/>
                </telerik:RadGridView.Columns>
            </telerik:RadGridView>

Hello,

I guess that the problem is related with the use of GridViewSelect column and the binding of the IsSelected property of the GridViewRow. However, can you try to execute your code using a dispatcher? Please give it a try and let me know how it works for you.

Yes, using a dispatcher is good to me. Thank you for your feedback.
